Long string of bad decisions have been made.
...I roll to seduce Tiamat.
Or, why I should never be allowed to have a Mythic-level bard. I will gleefully play into the trope, as Austin Powers-like as possible, baby, yeah.
That's the best way to take a single campaign and make it into a long-running universe. The last multi-year, same-story table I was a part of wound up spanning outwards specifically because one of the players did some shit way back at the end of Campaign #0 to spawn a demigod or two, which resulted in a world-seeding of demis on some Exalted-type shit. I miss it some days.
My level 9 party was supposed to fight Fafnir last week, but they spent too much time strategizing before entering the lair that they're going to fight him today.
they're epic level, they can probably handle it.
on the other hand, if they fight Szass Tam or Sul Khatesh...
Since when do RPGs have DMs?
Edit: Come on, y'all don't play dumb. We all know that there is a difference between an RPG and D&D.
Since every single ttrpg out there is hell bent on giving the “MC” a completely different name in each and every one of them, we'll just grab the most popular term and roll with it.
Also, this ttrpg concerns Tiamat, that one calls it a DM
